Spa Lights

Restore or upgrade spa and hot tub lighting with spa light replacement parts and assemblies from Hayward, Balboa Water Group, Waterway Plastics, Gecko Alliance, Pentair, and J&J Electronics. PST Pool Supplies stocks LED bulbs, lens assemblies, gaskets, niche O-rings, and complete light units for portable spas and in-ground gunite spas — starting from $9.90.

Spa lighting systems range from simple single-bulb lens assemblies to multi-zone LED color systems, but share the same failure points: burned-out bulbs, cracked or fogged lenses, and deteriorated gaskets that allow water intrusion into the niche. The key products in this collection: Hayward PureWhite Pro LED Spa Lamps (13W, available in 12V and 120V versions) are high-output LED replacement lamps producing 1,175–1,300 lumens — direct replacements for traditional incandescent spa bulbs with dramatically lower power draw and longer life. The Hayward Color Splash XGW 100 LED is a full RGBW color-changing spa light system with 50' cord included — a complete light assembly for spas wired for color LED systems. The Balboa Water Group 12V spa light (2-pin AMP cord) is the OEM light assembly for Balboa-controlled portable spas; the Balboa J&J adapter connects J&J light fixtures to Balboa control systems. Waterway lens assemblies — including the Mini (2-1/8\" face), fiber optic hex style, and 1/2\" threaded LED lens — provide replacement lens faces for Waterway light niches when only the lens is damaged. The Gecko IN.YJ2 LED replacement bulb (12VDC wedge T10) fits Gecko-controlled spa light fixtures. Gaskets and O-rings — the Aladdin G-228 spa light gasket, J&J Electronics SpaBrite silicone lens gasket, Jacuzzi 7-1/4\" silicon O-ring, and Pentair niche gasket set — seal light assemblies against water intrusion into the niche cavity.

The most common spa light failure is water in the light niche — when the lens gasket fails, water enters the fixture, causes bulb failure and can short the transformer. If your spa light flickers, fails frequently, or trips GFCI when activated, suspect a gasket failure before replacing the bulb. Drain below the light, remove the lens assembly, and replace the gasket before reinstalling. Always confirm voltage (12V or 120V) before ordering replacement bulbs — the two are not interchangeable and 120V bulbs in a 12V fixture will not light; 12V bulbs in a 120V fixture will burn out instantly.

Shop spa light parts at PST Pool Supplies and bring warm, clear illumination back to your hot tub or in-ground spa.

Frequently Asked Questions

Why does my spa light keep burning out or tripping the GFCI?
Repeated spa light bulb failures or GFCI trips are almost always caused by water intrusion into the light niche — not a bulb quality issue. When the lens gasket fails, water seeps past the lens into the light cavity and contacts the bulb socket. Water in the socket causes: (1) Premature bulb failure — moisture at the bulb base corrodes the contact and causes arcing that burns out the bulb. (2) GFCI trips — the current leakage path created by water in the niche triggers the GFCI, which correctly detects a ground fault. The fix is gasket replacement, not bulb replacement: drain the spa below the light, remove the lens assembly (usually 3–4 screws), dry the niche cavity completely, replace the lens gasket with a new silicone gasket, and reinstall the lens. Only after confirming the niche is dry and resealed should a new bulb be installed. Running a new bulb in a wet niche will fail the new bulb within days. Also check the light cord for pinching or abrasion — a damaged cord creates a similar leakage fault.
What is the difference between 12V and 120V spa lights?
The voltage rating defines how the light fixture receives power and which transformer or power supply it connects to: 12V spa lights run on low-voltage DC or AC power supplied through a transformer in the spa equipment cabinet. Most portable hot tubs use 12V lighting — the low voltage is inherently safer in a wet environment and the transformer is located away from the water. 12V bulbs include the Gecko IN.YJ2 LED (12VDC) and the Hayward PureWhite Pro 12V lamp. 120V spa lights run on line voltage and are more common in in-ground gunite spas wired with a dedicated 120V circuit to the light niche. In-ground spa lights use a sealed underwater niche (like a pool light niche) that physically isolates the fixture from the spa water, providing safety at line voltage. The Hayward PureWhite Pro 120V lamp is designed for these applications. Mixing voltages is dangerous: a 120V bulb in a 12V socket will not illuminate (insufficient voltage); a 12V bulb in a 120V socket will burn out instantly and may arc. Always confirm your spa's light system voltage before ordering a replacement bulb — check the existing bulb label or the transformer/control board output specification.
How do I replace a spa light lens assembly?
Lens assembly replacement restores a cracked, yellowed, or fogged spa light face without replacing the entire niche or wiring: (1) Turn off spa power at the breaker. (2) Drain the spa below the light location — most spa side wall lights are above the lowest drain point; use the spa drain valve and a submersible pump to lower the water. (3) Remove the lens retaining screws (typically 3–4 Phillips screws around the lens perimeter) and pull the lens assembly free from the niche. (4) Note the existing gasket condition — if the gasket is compressed or cracked, replace it (Aladdin G-228 or J&J SpaBrite silicone gasket as applicable). (5) Disconnect the bulb from the socket if replacing the bulb simultaneously. (6) Press the new lens assembly into the niche with the new gasket seated, align the screw holes, and install the screws — tighten evenly in a cross pattern to compress the gasket uniformly. (7) Refill and test. For Waterway Mini lens assemblies (2-1/8" face diameter), the lens threads into the niche body rather than using screws — thread clockwise until snug.
Can I upgrade my spa's incandescent light to LED?
Yes — upgrading spa lights to LED is one of the most worthwhile spa improvements. LED spa lamps offer: (1) Energy savings — a 13W LED produces equivalent or greater light output to a 100W incandescent spa bulb, reducing lighting power draw by 85–90%. (2) Longer life — LED spa lamps are rated for 25,000–50,000 hours versus 1,000–2,000 hours for incandescent bulbs. (3) Lower heat — LED bulbs run much cooler, reducing thermal stress on gaskets and lens assemblies. For a direct LED retrofit: confirm your existing niche voltage (12V or 120V) and select the Hayward PureWhite Pro in the matching voltage — it installs directly in place of the original incandescent bulb without any wiring changes. For a color LED upgrade on an in-ground spa: the Hayward Color Splash XGW system requires a compatible controller and a light niche that accepts the larger LED assembly — confirm niche compatibility before ordering. For Gecko-controlled portable spas: the Gecko IN.YJ2 LED (12VDC wedge T10) is the direct LED replacement for the OEM incandescent wedge bulb.
